Water control valve

This water control valve is specially designed for water medium regulation and on-off control, with a stable and durable structure, suitable for clean water, sewage, hot water and other water-based media. It adopts precision spool and sealing structure, featuring good regulation performance, low flow resistance and reliable sealing, effectively controlling flow rate and pressure in water pipelines. Made of ductile iron, stainless steel and non-toxic corrosion-resistant materials, it adapts to medium and low pressure working conditions in water supply and drainage, building plumbing, irrigation and water treatment systems. Supporting manual, pneumatic and electric actuation, it is easy to install and maintain with stable operation and long service life. Strictly tested for pressure and sealing performance, it ensures safe and efficient water flow control, widely used in municipal engineering, civil construction and industrial water circulation systems.

Automatic air release valve​
Automatic air release valve​
On top of HVAC piping, solar thermal systems, storage tanks, and industrial equipment, you can often spot a small brass or stainless steel valve. It requires no manual operation, yet quietly and automatically expels air from the system. This is a compact automatic air vent valve (also called an automatic air release valve). This article focuses on float-type automatic air vent valves ranging from DN15 to DN32, with bodies made of brass or stainless steel, providing a systematic explanation of their working principle, construction materials, installation methods, and application scenarios.

Air in water pipelines is a hidden threat to system efficiency and pipe longevity. Whether it takes the form of air pockets accumulating at high points in long-distance water mains or cavitation caused by negative pressure during pump start-up and shutdown, entrapped air that is not promptly expelled can reduce conveyance capacity, induce water hammer, and even cause pipeline rupture.
